  • Project Acronym:
    and marine ecosystems of the Mediterranean basin by integrating modeling and experimental tasks Specific objectives to be achieved are 1 To improve our capability to model the fate of Hg in the marine environment and specifically its translocation from one compartment to the other 2 To assess the qualitative and quantitative relationship between atmospheric input direct discharges to the sea and cycle of Hg in the marine environment and its re emission back to the atmosphere 3 To develop an integrated modeling system to be used in the implementation of the EU Directives 4 To apply this integrated modeling system for different environmental and socio economic scenarios for the evaluation of optimal emission reduction strategies and control policies In order to achieve these objectives MERCYMS is structured in five Work Packages WP which include a WP 1 on Data Bases that will provide the core of the input data to both atmospheric and water modeling systems as well as to socio economic analysis b WP 2 on the Integrated Modeling System which will include an atmospheric and a water modeling system will provide information on key parameters affecting the fate of mercury and its compounds in the marine and atmospheric ecosystems and their interaction at the air water interface global cycling c WP 3 on atmospheric and water measurements at coastal and off shore sites that will be used to validate and calibrate the modeling performance The validation and calibration of the integrated modeling system will be based on rigorous uncertainty analysis and optimisation procedures The results of the modeling simulations will represent the basis for the socio economic analysis tasks d WP 4 on the integration of the biogeochemical models WP 2 with socio economic analysis will focus on three specific scenarios including the Business As Usual BAU scenario

    will be used operationally to satisfy the requirements of HEllenic Navigation ESPEN is the most important target of this project In conclusion the targets of the project are distinguished in two main parts i The reliable nowcast and short term sea state weather forecast and ii The identification of criteria for passenger ships based primarily on seakeeping safety operability and passenger comfort in a wavy sea In regard to the first objective the targets are T 1 The development and implementation of a reliable coupled wind wave forecasting system and its evaluation by means of in situ measurements and satellite data Given that the reliable and prompt forecast of the wind field consist the most important factors in the reliable forecast of sea state the weather forecasting system should satisfy some important requirements apart of course of the good physics of the model such as fine spatial analysis speedy production of forecasting data and assimilation of real time measurements in the forecasting process etc The wave forecasting system will consist of two one way coupled models one offshore and one coastal wave forecasting model It is known that for the forecast of wave conditions in the coastal zone the use of shallow water wave models is required These models take into consideration all the relevant phenomena of wave propagation in shallow waters where bathymetry exhibits abrupt changes and the effects of currents could be important while they will utilize the offshore wave forecasts and the available local wave measurements by means of an appropriate numerical wave data assimilation scheme Special emphasis will be also given in the evaluation of wind and wave forecasting models by means of a local in situ measurements b data from the meteorological stations of the Hellenic National Meteorological Service as well as c ENVISAT satellite data in order to adopt the most reliable ones It is noted that for the first time in Greece 1 a tightly coupled wind wave forecasting system will be implemented 2 a systematic evaluation of the available wind and wave models will be performed and 3 a numerical wave data assimilation scheme for coastal wave forecasting will be developed T 2 The development and operation of a pilot warning system for hazardous wave and weather wind phenomena which could threaten coastal inhabited areas and sailing ships The definition of alarm levels will be based on statistical data and co operation with relevant entities Port Authorities General Secretariat of Civil Protection Local Government etc The same warning system will inform as well ships on route when the weather sea conditions near port of call are not fit for entry docking and maneuvering This target is also proposed for the first time in Greece T 3 The construction and operation of a handy low cost autonomous directional wave buoy of Greek technology which will be easily deployed and retrieved and will require limited effort and expenditure for maintenance This wave measuring device will be designed to operate in coastal areas but with a different anchoring system It will be able also to operate in offshore locations and fulfill today s and future s requirements of Hellenic and Mediterranean Operational Oceanography The target is the creation in the immediate future of a competitive product by international standards while in the frame of this project the data from this wave buoy as well as from the POSEIDON network buoys will be used for the evaluation and adaptation of the forecasting system It is noted that after the construction of the oceanographic station MEDOUSA from the Marine Technology and Development Company SA which is in the process of liquidation for the first time in Greece will be developed a flexible and low cost directional wave buoy of Greek technology T 4 The design implementation and production of a Wind and Wave Atlas for the Hellenic Seas based on a 10 year historical data The Atlas will be based to a great extent in hindcast results but will also include the measurements of the POSEIDON system for the years 1999 2004 The Atlas will be published in a printed as well as digital format CD The single other Wind and Wave Atlas for the Hellenic Seas was published in 1992 is out of print and is based on visual observations which have questionable reliability T 5 The design development implementation and operation of an advanced telecommunication system for the management and exploitation of the forecasting results and real time wave measurements This system will serve the communication requirements between ships port authorities which participate in this project and the operational centre which will be hosted during the project in the NCMR premises At the end of the project the complete software will be delivered to the Hellenic National Meteorological Service for servicing its operational needs while the Ministry of Merchant Marine will be the final end user of the system products In regard to the proposed project s second objective its targets are T 6 The development of a methodology for hazard identification and operability assessment of coastal ships in a given sea state In this methodology will be based the development of a decision making system for the departure control of RO RO ships and the necessity of imposing specific restrictions as e g determination of a particular route see also the following target T 7 The methodology that will be developed follows the general directions of Formal Safety Assessment which has been adopted by the International Maritime Organization IMO for the development of new rules The ship capability of facing given weather conditions will be assessed regarding several characteristics of her behaviour mainly concerning large amplitude ship motions in waves dynamic stability maneuverability etc The risk level concerning a particular voyage will be evaluated and the decision making system will be based on the comparison of the calculated index with an accepted one according to the existing international standards T 7 The development of criteria for the passengers comfort which will improve the quality
